SELF-CLOSING FAUCET.

SPECIFICATION formingpart of Letters Patent N 0. 665,631, dated January 8, 1901.

Application filed April 28, 1900. erial No. 14,655. (No model.)

To Cl/ZZ whom, it may concern:

Be it known that 1, WILLIAM DUFFUS, a citizen of the United States, residing at Chi cago, county of Cook, and State of Illinois, have invented new and useful Improvements in Self-Closing Faucets, of which the following is a specification.

My invention relates to improvements in self-closing faucets.

The object of my invention is, first, to provide a device which may be connected with the water-pipes of a building, like an ordinary faucet, or attached to the discharge end of an ordinary faucet, as desired; second, to provide means, when desirous for locking and holding the faucet in its open position after the hand of the user is withdrawn therefrom, whereby the same faucet may be used as a self-closing faucet or controlled by the operator, and, third, to provide a faucet which may be held open by the weight of a receptacle which is being filled therefrom and which will automatically close as soon as the receptacle is removed.

The construction and operation of my device are explained by referenceto the accompanying drawings, in which Figure 1 represents a vertical section of my device attached to the water-pipes of a building. Fig. 2 is a modified form of my device connected with the discharge end of an ordinary faucet and provided with means for locking the valve in its open position. Fig. 3 represents a horizontal section of the dischargenozzle, drawn on line 00 x of Fig. 1.

Like parts are identified by the same referonce-letters throughout the several views.

A is a coupling-collar by which my device is attached either to the discharge-nozzle B of an ordinary faucet, as shown in Fig. 2, or to the water-pipes of a building through a connecting-L O. The coupling-collar A is provided with a valve-seat D, from which the discharge-nozzle E is suspended by the valve F, and valve-stem G. The lower end of the stem G is connected to the discharge-nozzle E by the collar H and connecting-arms I. The lower end of the coupling-collar A is provided with an annular groove J for the reception of the upper edge of the nozzle E, the upper edge of which nozzle E is caused to enter said groove as the same is turned in any direction from the vertical.

It will be obvious that when the device is in its normal condition under water-pressure the valve F will be held firmly in position againstits seat D by the pressure of the water. When, however, it is desirous to open the faucet, it is simply necessary to press against the lower end of the discharge-nozzle in the direction indicated by the arrow in Fig. 1, whereby the discharge-nozzle will be thrown to one side of the vertical, and one side of the valve Fwill be raised from its seat, as indicated in Fig. l. The desired quantity of water having been drawn and the pressure against the side of the discharge nozzle being withdrawn, the valve will be caused to seat automatically, as stated, by the pressure of the water above it.

To avoid the liability of breaking a glass or other fragile receptacle when drawing water from the nozzle, as indicated in Fig. 1, I

preferably provide an elastic cushion K, which I is retained in place within the groove L of its 'own elasticity. When drawing water in a pail or other similar receptacle, the same may be suspended by its hail from the dischargenozzle upon the hook M, whereby said nozzle when thrown to one side will be retained in such position, and the valve F will be held open by the gravity of the receptacle suspended therefrom. When the receptacle is filled and the bail is removed from said hook, thevalve will be automatically thrown to its seat and closed by the pressure of the water Within.

If desirous to use my device as an ordinary faucet, the discharge-nozzle E may be held at one side of the vertical and the valve F retained in its open position by the eccentric N, which eccentric N is supported from the nozzle by the arm 0. The eccentric N is provided with an actuating-handle P. When the handle P is in the vertical position shown, the valve of the faucet will close automatically when released from pressure, and for ordinary purposes the faucet may bev so used. If, however, it is desirous to draw a large quantity of water, the necessity of holding said faucet open is obviated by swinging the handle P outwardly, whereby the nozzle will be tilted to one side and the valve will be raised from its seat and the water permitted to flow until such handle is thrown back to its normal position.

While I have shown the eccentric pivoted to the arm 0 and caused to bear against the side of the coupling-collar A, it is obvious that the converse of such arrangement of parts may be employed and said eccentric pivoted directly to the coupling-collar A and adapted to bear against the upper end of the arm 0. The form shown, however, is preferred.

It will of course be understood that When my device is attached to an ordinary faucet such faucet is left in the open position, the object of attaching my faucet to the ordinary faucet being to convert the same into a selfclosing device. My device may also be attached to faucets which have been worn out, and thus enable the user to provide means for controlling the flow of water at little expense, thereby avoiding the necessity of replacing the old faucet with a new one.

Having thus described my invention, What I claim as new, and desire to secure by Letters Patent, is-

I. In a faucet, the combination of a coupling-collar; a discharge-nozzle connected with and movable laterally upon said collar; a selfclosing valve supported from a seat in said coupling-collar; and a valve-stem connecting said valve and nozzle together, substantially as and for the purpose specified.

2. In a faucet, the combination of a coupling-collar; a discharge-nozzle con nected with and movable laterally upon said couplingcollar; an annular elastic cushion supported from the lower end of said nozzle; a self-closing valve supported from a seat in said coup ling-collar; and a valve-stem connecting said lever pivotally supported in connection with said discharge-nozzle, and adapted to bear against the exterior wall of said coupling-collar; a self-closin g valve supported from a seat in said coupling-collar; and avalve-stem connecting said valve and nozzle together, substantially as and for the purpose specified.

5. In a faucet, the combination of a coupling-collar; a discharge-nozzle movably connected with said coupling-collar; an elastic annular cushion connected with the lower end of said nozzle; a supporting-hook formed integral with said nozzle; an eccentric hearing supported from said nozzle and adapted to bear against the exterior wall of said coupling-collar; a self-closing valve supported from a seat in said coupling-collar; and a valve-stem connecting said valve and nozzle together, all substantially as and for the purpose specified.

lntestimony whereof I affix my signature in the presence of two witnesses.

WILLIAM DUI FUS.
